[Importance of carotid artery studies prior to coronary surgery].

The incidence of cerebral complications following extracorporal cardiac operations is reported to be approximately 2%. One of the possible reasons behind these complications is the presence of significant carotid stenosis as coexistent disease to the cardiac illness requiring surgery. Because of the common etiology carotid stenosis coexists mainly with a coronary artery disease. The authors make known their own screening methods based on the correct exploration of medical history and on the proper physical examinations. Coexistent significant carotid stenosis was revealed in 3.6% of 1056 patients who underwent coronary surgery within the period of 41 months. In all of these cases prophylactic carotid endarterectomy was performed. In twenty cases within this group the carotid reconstructions were performed simultaneously with myocardium revascularization. Staged endprocedures were performed in the other 18 cases. There was no surgical mortality and only one patient suffered major stroke. The authors emphasize the importance of carotid screening among patients awaiting coronary surgery especially in patients who previously sustained cerebral ischemic attacks, the presence of carotid bruits or any other known localization of obliterate arterial disease and finally in all patients over 60 years of age.
